This article describes roughly how signals are processed by the plc and are shown in the PVSS.
In this example we choose a pressure sensor.
- A signal from a pressure sensor is converted from analog to digital (A/D).
- the digital signal is integrated on the PLC at a defined place (here e.g. PIW 512)
- the digital signal is then converted and calculated by a lib (library) to the needed value. The FC (function) is "telling" the library to start the calculation.
- The result of the calculation is stored in a DB (database).
- From this DB it is transferred and visualized in PVSS.
All these actions take place in one PLC- cycle.
